BAG 0R SACK.

SPECIFICATION forming part of Letters Patent No. 683,894, dated October 8, 1901.

Application filed December 13, 1900. Renewed August 17,1901. Serial No. 72.381. (No model.)

T0 all whom it may concern:

Be it known that I, ADELMER M. BATES, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements lin BagsA or Sacks, of which the following is a full, clear, and exact specification.

My invention relates to improvements in valved bags or sacks of the class shown and described in my United States Letters Patent No. 623,199, issued April 18, 1900; audit has for its object to provide an improved and simple means of producing a valve-guarded filling-aperture in a bag or sack of this character.

With these ends in view my invention consists in certain features of novelty in the construction, combinatiomand arrangement of parts by which the said objects and certain other objects hereinafter appearing are attained, all as fully described with reference to the accompanying drawings and more particularly pointed out in the claims.

In the said drawings, Figure 1 is a side view, partly broken away, showing the manner of folding the bag to produce the valve; and Fig. 2 is a similar view showing a modification of the manner of folding the walls of the bag to produce the valve.

The forms of my invention shownin the figures are intended more especially for use on a bag which has its lower end sewed up and the bag turned right side out before the valved filling-aperture is produced. Thus in Fig. 1 it will be seen that the hem 11 at the bottom of the bag is turned inwardly, the side edges and the bottom end having been completely stitched on the machine or in any other suitable way-and the bag turned right side out before the end which contains the valved filling-aperture is closed. In the form shown in Fig. 1 the valved filling-aperture is produced by tucking a corner of the bag into its interior, as shown at 12, thus producing an inwardly-extending neck, after which a line of stitching 43 is run across the end of ing operation across the end of the bag and the folded corner completes the securing operation of the bags walls, and it is then ready for filling. The filling may be accomplished, as before described in my aforesaid patent, by inserting a filling-funnel or other suitable device through the neck 12, which will be automatically closed by the pressure of the material Within.

In the form shown in Fig. 2 I have deviated from that already described with reference to Fig. 1 only in that prior toy ruiming the line of stitching 4a. across the end of the bag to secure its side walls together I turn the side walls inwardly against the side of the bag-that is, fold them over, so that across the major part of the end there will be four thicknesses and across the tucked-in corner or neck 12 there will be six thicknesses, the stitching 4. being carriedv across the folded corner also and securing all six thicknesses together.

The exterior aps 1 and 2 are closed by the seam 4, and in Fig. 1 they are shown as left free, but in Fig. 2 as turned down on the side of the bag.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is

1. As an article of manufacture a bag having its side walls at one corner pushed inwardly solas to bring the outer faces of the side walls together and form an inwardlyprojecting neck and means vfor securing the side walls of the bag together across the end in which said corner is located and only partially-across said corner so as to leave a lilling-aperture guarded by said neck.

2. As an article of manufacture a bag having its side walls at one corner pushed inwardly so as to bring the outer faces of said side walls together and form an inwardlyprojecting neck and the side walls of the same end in which said corner is located turned over against the side of the bag and means' for securing said side walls together at said end and also securing said turned-over portion against the side of the bag.

3. As an article of manufacture a bag having its side walls at one corner pushed inwardly so as to form an inwardly-projecting neck and the side walls at the same end folded over against the side of the bag and partially ICI) of the nturnecl corner, so as to leave au 'operioversad corner and a line of stitching passing ing at said corner guarded by internal flaps.

across said folded end of the bag and corner.

4c. As a new article of manufacture, a ba@ s 1 formed substantially in the usual manne?` A' M' BA'lES 5 with one corner at the open end turned nlVtnesses:

F. A. HOPKINS,

Wardly, and a line of exterior stitching across said normally open end above the lower point J. E. CORNELL.
